Hi,

START_TIME :- "10-NOV-2009 00:00:04"
STOP_TIME :- "10-NOV-2009 00:05:47"

Please help to find difference between these two.

Searched for the same topic but did not find an answer for the same time format :frowning:

Regards,
Robin

Thanks a lot for your replay..

I have two variables

START_TIME="10-NOV-2009 00:00:04"
STOP_TIME="10-NOV-2009 00:05:47"

And now i need the difference in seconds in a third variable.

TIME_DIFFERENCE=$($START_TIME - $STOP_TIME)

so here i need the TIME_DIFFERENCE :slight_smile:

Can u help?
